Structural formula:
EINECS/ELINCS: 234-290-7
Tetrahydromethyl-1,3-isobenzofurandione is mainly used as a curing agent for epoxy resins. Tetrahydromethyl-1,3-isobenzofurandione has a low tendency to absorb moisture from the air and zero or minimal formation of carbon dioxide when mixed with tertiary amine accelerators.
Methyltetrahydrophthalic anhydride can be easily blended with various liquid resins providing stable, low viscous mixture and long pot lives.
Tetrahydromethyl-1,3-isobenzofurandionea lot of applications for the production of electrical parts such as: capacitors, resistors, wiring parts transformers, ignition coils, fly back transformers.
